What makes Micro ATX motherboards so popular for desktop computers? Find out if this form factor is right for you and how to choose a MicroATX motherboard right here.

When ATX and MicroATX (also known as mATX) motherboards were introduced back in 1995, ATX quickly took over as the most popular form factor for desktop computers while the compact Micro ATX fell by the wayside as a niche product.

Modern micro ATX motherboards also offer either 1 or 2 NVME slots, which can be used to install much faster NVME SSD for excellent storage access speeds.

Micro-ATX (37) E-ATX (29) 3.5' SBC. DDR4-2666MHz, in 16 DIMM slots; Up to 2TB Intel® Optane™ DC Persistent Memory in memory mode (Cascade Lake only. The ATX motherboard also assists in handling high-quality items and office computer programs. Benefits: High performance. Have four slots of RAM. Lots of PCIe Slots. Buyer: Larger sizes cannot be compared to standard computer cases. Micro ATX: The Micro ATX Motherboard was first introduced in 1997 by Intel. The size of the Micro ATX is 244 x 244 mm (9.6″ x 9.6″). On the other hand, the size of the Mini ITX is 170 x 170 mm (6.7″ x 6.7″). When you compare the size of them, the winner is the Mini ITX. Another thing to compare when talking about Micro ATX vs Mini ITX is RAM slots. For Micro ATX, it supports up to 4 memory slots. The ATX board has five expansion slots while the Micro ATX board has three expansion slots. The number of drive bays in a ATX form factor is more than that of in a Micro ATX form factor. A Micro ATX board can be installed in an ATX chassis but the other way is not around is not possible.

Fast forward to today and things are looking quite different - In recent years, Micro ATX has been steadily replacing ATX as the preferred form factor for mainstream consumers.

Why the newfound love for MicroATX? With more and more features integrated into the CPU and motherboard chipset, a large ATX motherboard with seven expansion slots is starting to look like overkill for most people. Current motherboards don't need a dedicated sound card, and integrated graphics has evolved to a stage where it's able to match low-end discrete graphics cards.

See the image below for a motherboard size comparison between MicroATX (24.4 x 24.4 cm, 9.6 x 9.6 in) vs. ATX (30.5 x 24.4 cm, 12 x 9.6 in):

When Should You Buy a Micro ATX Motherboard?

1. You are going after the cheapest possible motherboard

With a bit of homework and bargain hunting, you will discover most of the lowest-priced motherboards are MicroATX ones. This comes as no surprise, since the smaller Mini ITX motherboard calls for more refined manufacturing techniques while the larger ATX board requires more components.
On top of that, most Micro ATX cases are able to accept standard components such as ATX power supplies and full-height expansion cards so gives you more (cheap) choices for your other hardware as well.
That being said, we want to add that Micro ATX motherboards come at all price points... from the bargain basement boards to the top-end models with all the bells and whistles.

2. You want a compact computer for flexible placement

Some people prefer to have their computers on the desk while others rather have them sit on the floor. A Micro-ATX mini tower allows you to do both with comfort.
The diminutive Mini-ITX case looks good on a desk, but it's too short for you to leave it on the floor (you'll have to do a sit-and-reach each time to turn on the computer).
And sure, noone's stopping you from hefting a ATX full tower onto the table, but imagine the amount of workspace it's going to take up (assuming that your table is able to support its weight)... plus imagine the hassle if your USB ports, audio ports and power switch are located at the top of the case.

3. You want a computer that's good enough for most purposes

There are no official figures, but it's quite safe to say that a mATX motherboard are able to satisfy the needs of at least three quarters of computer users. Other than price, that's the other major reason for the Micro ATX form factor gaining widespread popularity with mainstream consumers.
However, being a jack of all trades also implies Micro ATX isn't the best form factor for some specific needs.
For example, the even smaller Mini-ITX is a better choice in general if you're building a home theater PC, NAS or a semi-portable computer. At the other end, power users such as serious gamers, overclockers, server admins and graphics designers will be better off with the full-sized ATX form factor.

RAM Slots

Most budget MicroATX motherboards have two RAM slots, while mid to high end models tend to offer four slots. So should you go for four slots or make do with just two?
The answer will depend on the intended use for your computer. We highly recommend that you read our 'How Much RAM Do You Need' article for more details.
Our general advice is to go for a motherboard with four RAM slots... Unless budget is a big concern or you're certain that two slots will suffice for now and the foreseeable future. You can always begin with two RAM sticks and leave two free slots in case you need more RAM for the future.

Expansion Slots

Micro ATX mainboards can have two, three or four expansion slots. Given that modern CPUs and motherboards come with tons of integrated features (e.g. video, audio, network capabilities), most light to moderate users will do just fine with two expansion slots.
What matters more (than the number of slots) is what type of expansion slots are on the motherboard. If possible, always try to go for PCI Express slots (unless you still have older expansion cards that make use of the outdated PCI slots).
If you intend to use your computer for gaming, then it's quite essential to have at least one PCI Express x 16 slot so you can install a discrete graphics card. Heavy gamers can go a step further and opt for Micro ATX motherboards that support multiple graphics cards (Nvidia SLI, AMD CrossFireX).

SATA Connectors

Every internal hard drive and optical drive requires an individual SATA connector. Modern mATX motherboards have at least four such connectors, which is enough for most users. What's more important is to make sure that you have at least one SATA 3 connector (vs. the slower SATA 2) if you intend to install a SATA 3 solid state drive.

Power Phases

In general, a motherboard with more power phases is able to deliver cleaner and more stable power to the CPU and RAM... allowing the them to hit higher overclocks. Having more power phases also means less load on motherboard transistors, prolonging their lifespan.
If you intend to overclock your CPU and RAM on a Micro ATX motherboard, it should at least have a 4 + 2 power phase (6 + 2 is better). 4/6 here is the number of phases for the CPU while 2 refers to the number of phases for the memory (RAM) controller.
All the power phases in the world is not going to matter if you don't have a high quality VRM (Voltage Regulator Module) to begin with. To avoid substandard VRMs, stick to reputable motherboard manufacturers: Asus, Gigabyte, ASRock, MSI.

Others

Whenever possible, always choose Micro ATX motherboards with USB 3.0 back panel ports and/or USB 3.0 front panel connectors. They make a big difference over USB 2.0 (two to four times real-world speed improvement) when you're hooking up your computer to USB 3.0 storage devices (flash drives and external hard drives).

The decision

Most PC gamers like to compare two motherboards especially the ATX and Micro ATX motherboard.
Both motherboards have a lot in common, they both use a power outlet and can hold a lot of extra spaces.
Boards have different variations that end up being different and suitable for different uses.
Gamers wishing to adopt any mother board should base their choice on a different thinking.
Some may prefer larger sizes with more spaces while others may prefer smaller clear boards.
First we will look at each different difference between the two motherboards before choosing the best gaming motherboard.

Size:

When it comes to size, the ATX format gets points.
This motherboard is slightly larger than its Micro ATX rivalry. Some ATX format models have extensions that make mamaboard very large.
Being large in size is a great advantage for gamers because you can add some additional features like SDDS and video cards to your PC.
Having a smaller size does not give the Micro ATX motherboard a lot of trouble. The small size can still run most video games without any drives and it is possible to use a small motherboard in multi-compact spaces.
For example, a small USB ATX board would fit the size of a large ATX model.
